Vehicle Conditions Incorrect for Particulate Matter Sensor Regeneration
The ECM detects that the vehicle is not operating in conditions suitable for the periodic PM sensor regeneration cycle. The sensor element cannot be cleaned and soot-mass measurement is paused.
Affected components
- Pm sensor
- Exhaust system
Common causes
- High likelihood: Driving cycle too short for regen conditions
- Medium likelihood: Sustained low-load operation
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- A drive cycle may be required after repair
